Any kind of purification or cleaning-up process is naturally and inevitably unpleasant or even painful

There are different kinds of purification or cleaning up process in the world of human beings.

There are endless 'rubbish' and 'messiness' being generated by human beings unto oneself and into the surrounding environment, that need ongoing cleaning/tidying up or cleansing activity, or else, all and everything will be 'drowned' by the excessive ceaseless and endless generation and accumulation of 'rubbish' and 'messiness', or ignorance and the consequences of ignorance, in the world that doesn't belong to anyone or anything.

There is the essential observation of maintaining internal and external cleanliness, or the engagement in internal and external purification/cleansing process in the teachings of yoga and buddhism.

Internal cleanliness is about the physical and mental purification process. 

Physical purification process to remove physical fatigue, laziness, idleness, under activity, over activity, energy blockage, stiffness, heaviness, sluggishness, inflammation, infection, illness, disease, and etc.

Mind purification process to remove the veil of ignorance, restlessness, cloudiness, murkiness, inattentiveness, passion, the idea of 'I', egoism of attachment, identification, craving and aversion, comparison, judgment, and expectation, and all kinds of impurities, to be free from the conditional restless impure egoistic thinking and behavior pattern under the influence of worldly passionate egoistic ideas, beliefs, values, desires, and practices, or to be free from the corrupted thinking and incorrect understanding and the consequences of that.

External cleanliness is about the cleanliness/tidiness and simplicity of the surrounding environment as well as the living space and the physical yoga practice space.

Not only the personal living space and yoga practice space need ceaseless ongoing effort for cleaning and tidying up regularly, but also the public space, community space, work space, all kinds of organization, political corruption, as well as natural disasters aftermath and/or ignorance inflicted events aftermath, and so on.

All kinds of purification or cleaning up process will naturally and inevitably give rise to some unpleasant and even painful side-effects or consequences.

Just like cleaning up the long time never been cleaned garbage container of intense stubborn stain and foul smell. It's extremely unpleasant and disgusting, but one needs to have the courage or indifference to confront all that during the process of cleaning up. And after that, one needs to have the consistent initiation and effort to clean up the garbage container regularly from time to time, and the cleaning process will become less and less unpleasant, and eventually, without any unpleasantness at all.

The process of eradicating any kind of impurities, or 'rubbish', or corruptions in the physical body, in the modification of the mind, in the diverse community, in all kinds of organization, especially in the world of corrupted politics, and in the surrounding environment, regardless of personally/individually or communally/collectively, is an unpleasant and exhausting ongoing process. Just as the ongoing maintenance or cleaning process of the garden. Just as the endless maintenance of life existence to be attending ceaseless hunger and thirst until the selfless impermanent life existence comes to an end.

The activation of the conscious mind purification process of eradicating the veil of ignorance, the idea of 'I', egoism, and all kinds of impurities or restlessness, is the same as the engagement in selfless actions of cleaning up/reforming process of eradicating all kinds of corruptions in the world of human beings, which is an extremely challenging and prolonged ongoing process.

All kinds of corruptions in the world of human beings are deriving from the corrupted minds functioning under the influence of the veil of ignorance.

Ignorance can only be eradicated by the mind itself, out of its own conscious awareness, freewill, initiation, effort, yearning for liberation, determination, and perseverance. 

Yoga and buddhism practice is all about the purification/eradication/elimination process of annihilating the veil of ignorance in the mind, by the mind itself.

It is greatly unpleasant and even painful for the mind especially in the beginning, and it might continuously be unpleasant and painful from time to time, until the mind developed the basic essential fundamental qualities/elements/disciplines, independence or self reliance, and correct understanding, that will eventually lead the mind towards the complete annihilation of the veil of ignorance, or the ultimate liberation from ignorance and the consequences of ignorance.

Similarly, the cleaning up or reforming process of the political corruption that exists in many areas or countries, that ceaselessly inflict and promote fear, violence, anger, hatred, unrest, destructive hurtful behavior, selfishness, possessiveness, greed, manipulation, exploitation, discrimination, and separateness among the diverse individuals and diverse communities in the world that doesn't belong to anyone or anything in order to gratified certain selfish agendas, aspirations, and desires of certain human beings, that affects the life existence of all and everyone locally and globally, is highly challenging, exhausting, and unpleasant.

The mind purification process, or conscious mind evolution of changing the conditional thinking and behavior pattern, can only be happening in oneself, by oneself.

All minds need to reform oneself, and naturally/eventually, there will be less and less corrupted minds in the world contributing any kind of corruption, or ignorance and consequences of ignorance into the world that doesn't belong to anyone or anything.

If there is fear or aversion towards the inevitable exhausting and unpleasant side-effects that arise during the process of cleaning up, where one is reluctant to be engaging in the individual and collective cleaning up process, but then, one will have to deal with all kinds of harmful effects of the ceaseless accumulation of impurities/corruptions/'rubbish'/'messiness'/ignorance and consequences of ignorance that are detrimental to the overall welfare of oneself and others and the surrounding environment, where there won't be any suitable conducive internal and external environment, for anyone or anything to be existing and functioning as what all and everything are.

Just as, there are many minds are reluctant to cut off 'ties and connections' with some 'bullies', and rather accepting all kinds of continuous endless 'bullying behaviors' of 'the bullies', empowering 'the bully and its bullying behaviors', because the minds think and believe that they cannot be independent, and that they have to rely on the bullies for 'something that they want'.

Inquire the truth of everything.
